### getOrCreate

    public static java.lang.Object getOrCreate(java.util.Map m,
                                               java.lang.Object key,

  Get a value from a map, creating a new instance of a class and inserting it as the default value if it's not found. This method synchronizes on the map argument and relies on toCreate to be a class with a default constructor.

  Parameters:
    `m` - Map to get value from
    `key` - Key into map
    `toCreate` - Class to instantiate and insert into 'm' if the key doesn't exist in the map.
  Returns:
    The value of the map in the key, or an instance of toCreate if not.
